CA will work if you use enough of it. I've used it before when I was in a hurry. Never had a problem in flight, but in a crash, it will usually come out. But if you have bad vibes, it could eventually crack and become loose. Plus with CA, you don't have much time to set the angle of the support ends.

I used CA on the mini rods, broke it putting the rods on the heli, the epoxy is a must IMO. Fast cure is prolly fine though (still gives you 5mins to get the angle right) and the heli makes a pretty decent clamp
